GEORGE T. REICHENBACH AND JACOB G. PECK, OF PORTLAND, OREGON, ASSIGNORS TO H. 0. PECK AUTOMOBILE WHEEL COMPANY, INCORPORATED, OF PORTLAND,

OREGON.

To all whom it may concer/n:

Be it known that we, GEORGE T. Fisici-inn* BACH and Jaoon G. Piton, both residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Resilient Spokes, of which the following is a specilicatioii. Y

Our invention is an improved resilient spoke for vehicle wheels, and the invention has for its object to provide a spoke that shall be light in weight, strong and nonbuckling when in use, simple' in its construction, and inexpensive to manufacture.

The invention resides in providing a spoke of the telescopic-section type, in which an outer cylinder is provided, through one end of which a piston rod passes, the rod carrying a specially constructed piston, and the cylinder head being closed by a specially constructed closure device that is light in weight, but strong and etlicient in use.

One of the great difficulties encountered in designing a spring` spoke wheel is to so produce a structure that will not be of an excessive weight and yet be su'lticiently strong to withstand the very great strains imposed upon the wheel in practice.

The invention also includes those novel details of construction, combination and arrangement ot parts, all of which will he irst fully described, then be speciiically pointed out in the appended claims, and

illustrated in the accompanying drawings,

in which Figure 1, is a vertical longitudinal section of a spoke embodying the invention. Fig. 2, is a detail section showing a slight modication. Figs. 3 and 4, are respective cross sections o-ii the line 33 and 1-4L on Fig. 1. In the drawings, in which like letters and numerals of reference indicate like parts in all of the figures, 1 designates the outer casing' which is closed at one end and formed with a hub bearing 2 that may be suitably bushed, as at 3, it desired, and whose other end is internally threaded at 4L, and provided with a shoulder 5 to receive the web 10 of a bearing sleeve 11u12. The web 10 has a teat 111 to rest in a recess 6 iii the shoulder 5 to prevent the sleeve from turning. Threaded into the end 4f of the cylin der 1 is a hollow nut cap 7 which, when ansimnivr sroKE.

screwed home, jams the web 10 on the shoulder 5. The nut cap 7 has an opening through which the piston rod 15 freely projects. Surrounding the rod 15 within the cap 7 is a packing 9 which rests on the flange 13 of the upper end' 120i the `sleeve 11-12', to form an oil-tiglit closure for the cylinder l. 'The rod 15 has a bearing end 16 that may be suitably hushed at 17, if desired.

In order to reduce the weightof the spoke as much as possible without decreasing its strength, the rod 15 is made tubular and the lower end is closed by a cap 21 which is threaded at 18 onto the rod 15. The rod 15 has a shoulder 19 and carries a 'washer 2O which closes the chamber 22 in the cap 2l. A pin 23 holds the cap 21 from turning oft'. The usual spi-ine' 2st is employed to telescope the spoke sections 1 and 15.

In practice the pocket 22 is filled with lubricant which will How out through the pin hole 23 and lubricate the piston formed by the cap 21 and washer 20, the pin hole being made larger than the pin for this` purpose.

From the foregoing description it will be seen by the construction shown and de i scribed a relatively light spoke is obtained `without sacrificing strength and the necessary bearing for the section 15 at the head of the spoke which is minimum weight.

Instead of making the sleeve section 1Q integralwiththe web 10, it may be as a separate element 24a, as shown in Fig. 2 of the drawings, and when that is the case, it is provided with a flange 25 in addition to the flange 13a so as to rest on the web 10 andprevent rattling, the flanges 13a and 25 extending the full diameter of the cap 7 so as to make a relatively rigid contact therewith. v

l/Vhat we claim is 1. A resilient spoke for vehicle wheels and the like comprising a cylinder, a piston rod projecting into said cylinder, apiston in said cylinder including a cap threaded onto the end of said piston rod, said cap having a pocket opening at the top, a washer on said piston rod for closing said pocket, a pin hole passing through said cap and piston rod, and a pin of lesser diameter than provided with the said pin hole held in said pin hole and a cushioning means within said cylinder c0- operating with said piston.

2. In a resilient spoke for vehicle Wheels and the like, a cylinder section having an open end, a piston rod projecting through said open end, said cylinder having a seat adjacent to its open end, a. Web held on said seat, a tubular cap threaded int-o said open end of said cylinder to engage said Web and retain it on its seat, said Web and said cap having an aperture to permit passage of said piston rod, vand a rod packing carried Within said cap and a cushioning means Within said cylinder coperating With said piston.`

4:. I1 a resilient spoke for vehicle Wheels and t like, a cylinder section having an open nd, a pistonrod projecting through said pen end, said cylinder having a seat adja en t to its open end, a Web held on said seat, a tubular cap threaded into said open end off said cylinder to engage said web and ret-ain it on its seat, said web and saidcap` havin@ an aperture to permit passage of said piston rod, a rod packing carried Within saijd cap, and a tubular`bearing sleeve for said piston rod carried by said Web, and alicushioning means Within said cylinder co erating with, said piston.

5. In \a resilient spoke foi" vehicle Wheels and the like, a cylinder` section having Aan open end, apiston rod projecting through said open end, said cylinder havinga seat adjacent to its open end, a'iveb held on said seat, a tubular cap threaded into said open i end of said cylinder to engage said web and retain it on its seat, said Web and said cap having an aperture to permit passage of said piston rod, a rod packing carried Within said cap, a tubular bearing sleeve for said piston rod carried by said Web, said bearing sleeve having a iiange at its upper' end to engage said cap, said rod packing being mounted between the apertured end of said cap and said flange and acushioning means 'ivithin said cylinder coperating with said piston.

,6. In a resilient spoke, a piston rod, a piston carried by said piston rod, and a cylinder in which said piston operates, said piston including a cap secured over the end of said piston rod and having a lubricant pocket opening at the top of the cap, a -:Washer-carried bysaid piston rod t0 close said lubricant pocket-,"sa-idcap having lubricant conveying holes for conveying said lubricant to the outside of said cap and a cushioning means Within said cylinder coperating with said piston.
